To all whom it may concern:

Be it known that I, AsA SEELEY, acitizen ofthe United States of America,residing at 1004 West Washington street, in Bloomington, McLean county,Illinois, have invented certain new and useful Improvements inI-Iydraulic Mains, of which the following is a specification.

This invention relates to new and useful improvements in hydraulic mainsemployed in gas generation and it is anobject of the invention toprovide a novel device of this `character wherein the trouble caused bythe stand pipes becomin sto ed or clo `ed with lamp black or pith isrldduced to a ngiinimum.

It is also an object of the invention to provide a novel device of thischaracter wherein the stand pipes enter the main from the bottom insteadof at the top as is the well known or ordinary practice now employed.

Furthermore, it is an object of this invention to produce a device ofthe character noted, which will possess advantages in points ofsimplicity, efficiency and durability, proving at the same timecomparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists inthe details of construction and in the arrangement and combination ofparts to be hereinafter more fully set forth and claimed. In describingthe invention in detail, reference will be had to the accompanyingdrawings forming part of this'speciiication wherein like charactersdenote corresponding parts in the several parts, in which- Figure 1, isa view partly in front elevation and partly in section of the invention.Fig. 2, is a top plan view. Fig. 3, is an end elevation. Fig. 4, is abottom plan view.

In the drawings 1, denotes the body of the main which is preferablyrectangular in form, and provided on its back face with the pockets 2,provided with the hinged covers 3, whereby access may be had to theinterior of the body to cleanse the same of lamp black' or pitch thatmay accumulate therein. One end of the body is provided with an opening4, which acts as an overflow for the water which is placed within thebody 1, as is well known in devices of this character. In the bottom ofthe body 1, approximately centrally thereof is an opening 5, for theremoval of pitch, which may accumulate therein. The top of the body 1,is provided with an opening 6, which is the gas outlet.

Extending within the body 1, through the bottom, are the upright pipes7, which terminate at a point adjacent the top of the body 1. Dependingfrom the top of the body 1, and surrounding the upper portion of theupright pipes are the short pipes 8. Sufficient water is placed withinthe body 1, to form a seal between the upright pipes 7 and the shortpipes 8. The gas passes through the upright pipes 7, down the shortpipes 8, through the water within the body 1, and is discharged throughthe outlet opening, thus it can be seen that this hydraulic mainproduces an effective medium whereby the gas is prevented from returningto the retort after it once leaves the retort.

The upper ends of the short pipes 8, are closed by the lids or seals 9,which are provided on their tops with the ears 10, between which arepivoted the ends of the bell levers 11. Each of these bell levers ispivoted in a bracket l2, fixed to the top of the body 1. To the free endof each of the levers is secured a suitable connection leading to leverspreferably positioned on the floor whereby the lids or seals of theshort pipes 8, may be raised when the retort with which the uprightpipes are connected is being drawn.

By having the lever 11, pivoted between the ears 10 on the tops of theseals, the seals are effectually held against assuming an inoperativeposition. In, other words, by this arrangement the seals are so held asto properly engage the upper ends of the short pipes 8. It is thoughtthat this structure can be readily understood from Fi 3, wherein it isnoted that any movement o the seal 9 on the lever 11 will be limited bycontact with said lever.

What I claim is:

In combination with a hydraulic main, pipes extending vertically throughthe bottom of the main and terminating near the op thereof, pipes n thetop of the main eX- mttng the faces of theseals to swing parallel ndingover the upper ends of the upright to the top main. 10 pes, removableseals for the p' es n the ln testimony wl1ereof,l my signature to of themain, ears on the tops or the seals, in the presence of two witnesses.
